In the figure, a slab of mass m1 = 40 kg
rests on a frictionless floor, and a block of mass
m2 = 8 kg rests on top of the slab. Between
block and slab, the coefficient of static friction is 0.60, and the
coefficient of kinetic friction is 0.40. A horizontal force F of
magnitude 105 N begins to pull directly on the block, as shown. In
unit-vector notation, what are the resulting accelerations of
(a) the block and...
